Opana and Bodybuilding

So today i had a killer shoulder/tri workout and i just injested about 15mg of opana(oxymorphone). I almost never use drugs/alcohol but tonight i was offered and i said **** it. Will injesting such a small amount of opiate affect my recovery and gains negatively or could there possibly even be a positive outcome regarding bodybuilding. Ps-yes i realize the highly addictive qualities of these drugs, especially opana because its the strongest painkiller commercially available, but im here to have a discussion on opiates and bodybuilding and get some insight from those who have used opiates and bodybuild( i.e. several bodybuilders use nubain which is an injectable opiate but have great physiques.)
